Staff
from the Idaho Public Utilities Commission will be in eastern Idaho on Sept. 21
and 22 to conduct public workshops regarding a rate increase request from Rocky
Mountain Power.

Last
June, Rocky Mountain Power applied for an average 13.7 percent increase. The
commission suspended the case for up to six months at that time to allow its
staff of auditors, engineers and attorneys to review the request.

Part
of that review process includes public workshops and hearings for customers.
The first of those workshops in scheduled for Tuesday, Sept. 21, at the
Robinson Building, 186 W. Second North in Preston. The second workshop will be
Wednesday, Sept. 22, in the Fremont County Annex Meeting Room at 125 N. Bridge
St. in St. Anthony. Both workshops begin at 7 p.m.

The
purpose of the workshops is for commission staff to explain the company’s
request and the process the commission must follow in considering that request.
After the staff’s presentation, the public will be able to ask questions.
Representatives of the company may also be on hand to answer questions, but are
not part of the staff’s presentation.

A
technical hearing in Boise is scheduled to begin Nov. 30 and public hearings in
eastern Idaho will likely be scheduled, also in mid- to late-November.

The
commission has received a number of written comments from customers asking that
the commission deny the request, especially given the current economy. However,
the commission cannot, by state law, arbitrarily refuse to consider utility
rate increase requests. State statutes require that all rate requests be
considered by the commission to determine whether the expenses the utility
seeks to recover through customer rates were necessary to serve customers and,
if necessary, were those expenses prudently incurred. The commission is free to
accept, reject or modify the company’s request. The commission may deny
expense recovery to a utility if the utility fails to provide evidence that
adequately supports the new expenses as needed to serve customers and prudently
incurred. All commission decisions can be appealed to the state Supreme Court
by the utility, intervenors or customers.

Parties
who have intervened in the case to present evidence, cross-examine witnesses,
participate in settlement conferences and make and argue motions include Agrium,
Inc. (Nu West), the Idaho Irrigation Pumpers Association, the PacifiCorp Idaho
Industrial Customers, the Idaho Conservation League and the Community Action
Partnership Association of Idaho (CAPAI). CAPAI represents primarily customers
on low and fixed incomes.

Rocky
Mountain Power states the increase is needed to cover expenses for more than $4
billion of new plant investment and $87 million in increased power supply
costs. Investments proposed in this case are already serving customers or will
be by the end of 2010. Those include eight new wind generation plants, a
345-kilovolt transmission line from Downey to Salt to Lake City, environmental
improvements at the Dave Johnston, Huntington and Jim Bridger power plants,
turbine upgrades at the Hunter, Huntington and Jim Bridge power plants and
hydro power relicensing and upgrade investments.

About
30 percent of the requested additional yearly revenue requirement of $27.7
million is due to increases in power supply costs which include expenses
related to fuel, purchases of power from the wholesale market and transmission
wheeling. The largest contributors to the proposed increase in power supply are
increasing coal costs and the replacement of older power supply contracts that
had lower prices with newer, higher-priced contracts.

According
to testimony filed by the company, lower load projections and current economic
conditions have resulted in Rocky Mountain scaling back some transmission and
distribution capital expenditures from previously planned levels. The company
has reduced its 10-year capital budget from nearly $2.2 billion per year to
$1.6 billion annually and plans no investments in new company-owned generation
until 2014.

Despite
those reductions, Rocky Mountain asserts it still must continue its multi-year
program of investing in renewable energy, transmission facilities and
environmental controls. “It is critical that rates reflect the current and
actual costs of serving our customers,” said Richard Walje, company president.
“Absent the increase requested in this case, the company will not receive the
revenue it requires to fund the future capital investments necessary to provide
reliable service to our customers.”

Responding
to a directive from the commission after the company’s last rate case, Rocky
Mountain is proposing a two-tiered rate structure for residential customers
under which customers pay more when their use exceeds 800 kWh per month.
Customers who stay below the company’s average residential use of 839 kWh year-round
will pay only about 1 percent more per year under the company’s proposed rate.
However, larger users will see substantially large increases if the application
is approved.

The
proposed winter rate (November through April) for the first 800 kWh of use is
6.55 cents per kWh. For use above that, the proposed rate jumps to 8.84 cents.
The current winter rate for residential customers is about 8 cents per kWh.

The
proposed residential summer rate for the first 800 kWh is 8.95 cents per kWh.
Use above that is proposed to be about 12 cents. The current summer rate is
about 10.4 cents.

Proposed
increases for customer classes vary according to the cost the company incurs to
serve each customer class.

The
company’s proposed increase for residential customers, including all energy and
customer service charges, is about 8 percent.

For
residential customers who are on optional Time of Day Rates, the proposed
increase is 15.6 percent. However, the average rate for a time-of-day customer
would still be about 1.35 cents per kWh lower than standard residential rates,
according to the company’s application.

The
proposed increase for small general service customers is 10.8 percent, for
medium- and large- general service customers, 14.6 percent; for irrigation customers,
9.6 percent; and large industrial from 15.9 percent to 19.6 percent. The
proposed increases for Rocky Mountain’s large contract customers are 19.6
percent for Monsanto and 15.9 percent for Nu-West.

The
company’s last rate case was filed in September 2008 when Rocky Mountain
requested a 4 percent overall increase. That case was settled in April 2009
when the company was granted a 3.1 percent increase.
